To all lwhom it may cbncern: l

Beit knownthat I, WILLIAM M. GIBSON, of Phenix, in the countyv of Kent and State of Rhode Island, have invented certairfnew and useful ImprovementsfinPumps; andi 'hereby Fig. 3 is an end view' of the pump; Fig. 4, a

plan view of the pump-valve. Fig. 5 is a sectional view of thue valve, and Fig. 6 is a sectional view of the leather cup and valve.

The invention has reference to the kind of pumps knownas deep-well pumps, in which the pump proper is placed within the well, and either at such distance above the water as will insure easy suction, or below the water-level, and the water forced to the surface.

It consists, iirst, in the peculiar arrangement of the inlet and outlet pipes connected with the air-chamber, by which the actuating-rod is placed so as to be on a line with the axis of the pump-cylinder.

It also consists in the peculiar and novel arrangement of the stirrup and the pump-cylinder, and the novel construction of the bucketvalve and valve-cup, as will be more fully described hereinafter, and pointed out in the claims. v

In the drawings, a is the suction-pipe, which maybe provided at its-lower end with a strainer. When, however, the pump is used as a submerged pump, in place of the suction-pipe a the strainer is placed on the cylinder end b, within which -the foot-valve c is secured. d represents the pump-cylinder, of copper, brass, or other metal, secured between the cylinder ends b and e, the whole being held together by rods passing through the ears b b' and E E', and securely held by suitable screw-nuts. The rods f f may preferably form the stirrup, and unite with the pump-rod j"2 at f1, either by securing the ends to a union-piece,l as shown, or otherwiseuniting the same.

gis a stationary bucket-valve, provided with a checkvalve, and secured by a cup-shaped PAT-ENT rIIENIx, RHODE I sLAnnf.,` 1 IN LIFT-PUMPS,

application led structiony of` this valve-bucket is peculiar, 'and is'shown enlarged in Figs.' 4, y5, and 6. The leath er cup forming the packing of -the valve on the sides of the pump-cylinder is made in one piece with the check-valve, and is secured to th'e valve-cup by three screws. g1 is the metal bucket g2, the leather cup, forming, also, the check-valve g3, the whole being secured to the valve-cup g1 by three screws, g, forming a cheap and simple bucket-valve for a pump which can be usedV for either a simple lift-pump or for lift and force pumps. The leather cup can be readily secured by the screws g4, and as readily removed or replaced.

The air-chamber l, cast in one piece with the chamber K, has the receiving-pipe h and the discharge-pipe 'i secured to it in such a manner that the two pipes will be offset sufciently to allow the actuating-mdf2 to reciprocate with the pump-cylinder in a straight line with the axis of the cylinder, thus preventing all binding and straining on the piston or bucket-valve,insuring uniform wear and ease in its operation. f3 is a guide-collar, through which the actuating pump-rod f2 passes, and is secured to the delivery-.pipe i by means of one or more keys. l is a pin, which may be provided with a screw and nut at its lower end, and is used to secure the pump in its proper position in the well. m represents a piece of timber, on which the pump rests.

The operation of the pump, whether sub merged or placed above the water-level, is as follows: The pump-cylinder being raised by the pump-rod f2, the water is forced through the check-valve g3 and through the pipe h into the delivery-pipe i, from the upper end of which it is discharged. When thepump-cylinder commences to descend, the check g3 closes, a partial vacuum is created in the pump-cylinder, and the atmospheric pressure forces the the upward stroke of the same.

The pump-cylinder can vbe readily taken apart, and all parts of the pump examined and repaired. It can be cheaply built, and used in wells of any depth, either as a submerged or an ordinary pump. As the strains are on the axial line of the cylinder and bucket-Valve, it

The combination, with the bucket-valve of apump, of the leather cup g2, arranged to form the packing of the bucket and the check-valve in one piece, substantially as and for the purpose described.

2. The combination, with the bucket g1, of the leather cup gz, forming the packing and the check-valve in one piece, and the screws g, arranged to secure the leather, substantially as and for the purpose described.

3. The combination, With the air-chamber l and chamber k, of the pipes h and i, arranged to form an offset, so that the actuating-rod' can be .operated on a line with the axis of the pump-cylinder, as and for the purpose described.

4. The combination, with a reciprocating pump-cylinder, of the pipe 7i, chamber k,and

pipe i, and the rods f f secured to the cylinder, the rodf, and guide f 3, the Whole arranged and operating substantially as and for the purpose described.

5. The combination, with the tube d, of the end E, provided with the ears or lugs E' E', the end b, provided with the ears b' b', and the rods f f, arranged to form the reciprocating pump-chamber, substantially as and for the purpose described.

6. The combination, with a pump arranged substantially as described, of the pin l', arranged to support and secure the pump, as and for the purpose described.
